DEVELOPING-MACHINE FOR PHOTOGRAPHIC FILMS.

Specification of Letters Patent.

Application filed September 4, 1908. Serial No. 451,727.

To all whom it may concern:

Be it known that I, ELIZABETH A. TAY- LOR, a citizen "of the UnitedStates, and a resident of Steilacoom, in the county of Pierce and Stateof Washington, have invented a new and Improved Developing- Machine forPhotographic Films, of which the following is a full, clear, and exactdescription.

The invention relates to developing machines for photographic films, andconsists of a plurality of cylinders of different diam eters, disposedone within the other respectively, each of the cylinders having alongitudinal slot therein. Rollers are mounted to revolve at the sidesof the slots to prevent the film from becoming scratched, and there is ameans by which one of the ends of a film may be secured to one of thecylinders, which will permit the film to be drawn out as the cylindersare rotated, means being provided to rotate one of the c linder's. Thereis. a projection on one'o the cylinders, which is adapted to engage aprojection which is secured to an ad oining cylrnder. Means are providedto rotatably mount the film so that it may be drawn out around thecylinders. A brake is provided by means of which the rotation of thecylrnders may be controlled, and there is an opening in the outercylinder, a pipe being secured thereto, the other end of the terminal ofthe pipe being secured to a graduating glass. Each of the cylinders maybe made in two halves and without one or both heads, the halves of thecylinders being hinged together, and one of the heads being made in theform of a cap, so that it will hold the halves together when it is inplace over one of the ends of the cylinder.

Still other objects of the invention will appear in the followingcomplete descrip tron. 1

In this specification I will describe the preferred form of myinvention, but it will be understood that I do not limit myself thereto,as I consider myself entitled to all forms and embodiments of theinvention which may be held to fall within the scope of the appendedclaims.

Reference is to be hadto the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, in which- Figure '1 is aperspective View showing one form of my invention, the parts beingbroken away to show the inner cylinders; Fig. 2 is a sectional view onthe line 2-2 of Fig. 3; Fig. 3 is a sectional view on the line 3-3 ofFig. 2; Fig. 4 is a view similar to the view shown in Fig. 2, but withthe film disposed around the inner cylinder; Fig. 5 is a cross sectionalview of another form of my invention; Fig. 6 is a longitudinal sectionalview of the form of my device shown in Fig. 5; and Fig. 7 is aperspective .view showing a modification in which the halves of acylinder are hinged together and a cap is provided for holding thehalves together.

By referring to the drawings, it will be seen that in. the form of myinvention shown in Fig. 1, I provide a casing 1, to which are securedsupports 2, the casing 1 having a cover 3, which may be removed, inorder that the operator move a film roll 4. In the casing 1, are d1sposed three cylinders 5, each of the cyhnders having a longitudinalslot 6 therein, the cylinders being of difierent diameters and beingdisposed one within the other respectively. At one or both ends of thecylinders there are openings 7 to permit them to communicate with thecasing 1.

on a shaft 8, to which the innermost cylinder is secured, the othercylinders being free to revolve relatively to the shaft 8. At the sidesof each of the longitudinal slots are 'rotatahly disposed rollers 9, theobject of these rollers being to prevent a film 10 from becomingscratched against the sides of the said slots, but inasmuch as the film10 is secured (see Figs. 2 and 4:) to one side of the slot in theinnermost cylinder 5, it is unnecessary to guard this side 11 by one ofthe rollers 9. The innermost cylinder has a projection 12 on itsperiphery. The outer cylinder 5, has an inwardly disposed projectionlSand the cylinder 5 disposed between the innermost and outermostcylinders, has projections 14:, one disposed outwardly and the otherinwardly. When the slots 6 of theseveral cylinders are in alinement andthe device is in position for operation, the projection 12 on theinnermost cylinder is at one. side of the projections 14 on the nextadjoining cylinder, and the projection 13 on the outermost cylinder ofthis projection 14. A hinged shelf 15 is Patented Oct. 26, 1909.

may place in position and re- The several. cylinders 5 which, as hasbeen stated, are

disposed one within the other, are mounted is at the other side providedon one side of the interior of the casing 1, and on this shelf may bedisposed the film roll 4, the shelf having a roller 16 on its edge, toprevent the film 10 from becoming scratched as it is drawn over theshelf. At the bottom of the casing lthere is an opening 17 and to thisopening 17 a rubber tube 18 is secured, the other end of the rubber tube18 being secured to the bottom of a graduating glass 19. A brake 20projects through the top of the cover 3 and it is adapted to projectthrough the slots 6 in the cylinders 5 at one side, so that it willprevent the cylinders from rotating. The end of the paper on which thefilm 10 is carried, is secured at one side of the slot 6 in theinnermost cylinder 5, by a clamp shown at 11.

In the other form of my invention, shown in Figs. 5 and 6, a crank 21 isjournaled to one side of a support 22, and a stud 23 is journaled to theother side of the support 22. The cylinders of different diameters aredisposed one within the other in the same way as in the constructionshown in Figs. 1 to 4:. In the construction shown in Figs. 5 and 6, theoutermost of the cylinders 24 is secured to the crank 21 and the othercylinders are adapted to rotate relatively to the said crank. The otherends of the cylinders are mounted to rotate on the stud 23. Thecylinders with the exception of the outer one, have longitudinal slots25 therein, and there are rollers 26 rotatably mounted at the sides ofthe slots in the same manner as has been described with reference to theother form of the invention. A film roll 27, is mounted to rotate onprojections 28 and 29, which extend from the crank 21 and the stud 23respectively. The projection 29 is in the form of a stem and is disposedin an opening in the stud 23. To'this stem is secured a gear wheel 30,around which there is disposed a brake 31, the brake having a rack 32 onone of its .sides. The brake 31 is adapted to extend up through theslots 25 in the cylinders to prevent them from rotating, and the rack 32meshes with the gear wheel 30 so that when the stem 29, to which thegear wheel is secured, is rotated, the brake 31 will be moved upwardlyor downwardly, to pass through the slots in the cylinders as has beenstated. A thumbscrew 33 passes through the stud 23 until it engages thestem 29, so that when the thumbscrew is screwed down, it will hold thestem in place and prevent the movement of the brake 31 relatively to thecylinder. There is a proection 34 on-the inner surface of the outercylinder 24; there is aprojection 35 on the outer surface of, theinnermost cylinder 24 and there are inner and outer projections 36 onthe remaining cylinders 24, which are disposed between the innermost,cylinder and the outermost cylinder. These projections mass? are adaptedto engage each other so that when the outer cylinder is rotated, it willdraw the film around once, when it will contact with the projection onthe next inner cylinder, and as the outer cylinder continues to rotate,it will cause the adjoining cylinders to revolve with it, until anotherrotation is completed, when the third cylinder will be caused to rotate,because its projection will contact with the inner projection on theneighboring cylinder which is disposed around it. In the outer cylinderthere is an opening 37 which is plugged by a cork 38, and this cork 38may be removed and the rubber tube 18 may be connected with the opening37.

In using the invention, the brakes 20 or 31 are disposed through theslots in the cylinders to prevent their rotation; the film roll isdisposed either on the shelf 15 or is mounted on the stem 29 and theprojection 28, after which the end of the paper on which the film 10 iscarried, is secured either to one side of the slot on the innermostcylinder in one form of the invention, or to the projection 34 on theoutermost cylinder in the other form of the invention.

In the construction shown in Figs. 5 and 6 in the drawings the film roll27 is mounted to rotate on projections 28 and 29, by removing the caps39 which close one set of ends of the cylinders 24:. A rubber band 40 isdisposed around the joint made by the cap 39 and the outer cylinders 24,to make it light-tight and the inner cylinders 24 have openings in theirends to permit the developing fluid to circulate. After the film roll isadjusted the brake 20 or 31, is then moved to permit the cylinder towhich the film is secured to rotate, and after one rotation the brake isagain moved to permit the next adjoining cylinder to rotate and so onuntil the film is wound around the several cylinders; Fig. 4: showingthe film wound around the innermost cylinder and partly around the nextadjoinin cylinder in one form of the invention, and Fig. 5 showing thefilm wound around one of the outer cylinders in the other form of theinvention. As has been stated, when one cylinder has made a completerevolution, the projection secured to it will cause the next adjoiningcylinder to rotate, and so on, until all the cylinders are connected andare rotated together and the film is wound around the several cylinders,there being one layer on each cylinder. The rubber tube 18 is thenconnected with the device, and a developing fluid is poured into thegraduating class 19 and the glass is raised above the device so that thefluid will run from the rubber tube into and between the cylinders, thecylinders having the openings 7 at their ends in both forms -ofconstruction. The cylinders are then rotated together, so that thedeveloping fluid will teeter reach all parts er the film, and when thefilm has been subjected to the action of the developing fluid for asufficient period of time, the graduating glass is lowered, to permitthe developing fluid to run out through the rubber tube into thegraduating glass. The developing fiuidis' then removed from thegraduating glass and water is substituted in place of it. The graduatingglass is again raised to permit the water to pass through the rubbertube into the device, and the cylinders are again rotated to wash thefilm. The water is then drawn off and the fixing solution is introducedinto the device in the same way, the cylinders being rotated to permitthe fixing solution to reach all parts of the film. Then the film isagain Washed, after which the Water is drawn oil and the film is removedfrom the device.

Bi the modification shown in Fig. 7, the cylinder is cut into halves 42,one of the heads of the cylinder being removed, and a cap 39 beingprovided, to be disposed over the headless end to hold the halves of thecylinder together. The cylinder shown in Fig. 7 is the outer one used inthe construction shown in Figs. 5 and 6 of the drawings,

but it is obvious that a slot may be made in the cylinders so that the.film may pass out at its periphery in the manner shown in connectionwith the inner cylinders.
